Product details

That 50 A hold means it'll handle a 50 A continuous load without nuisance tripping in a warm panel — out here in the grease, that's the number that keeps a motor feeder from dropping out mid-shift.

Interrupting duty and release

Interrupting ratings are 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V (–). The TM240 thermal-magnetic release is fixed — no field-adjustable trip curve, so the selectivity study needs to account for that fixed characteristic. Four HQ auxiliary switches come built in, giving you status feedback without adding a separate side-mount block.

Mounting and fit

The 3VA frame is designed for DIN-rail or screw-mount panel integration — the 70 mm depth keeps it within typical enclosure clearance for a 3-pole MCCB.

Frequently asked questions

Where can I buy 3VA1150-3EF32-0AE0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is 3VA1150-3EF32-0AE0's interrupting rating at 240 V?

The interrupting rating is 75.6 kA at 240 V. That is the maximum fault current it can safely clear at that voltage level.

Will 3VA1150-3EF32-0AE0 drop into a panel that was specified around 3VA1010-2ED42-0AE0 without rewiring?

Both are 3VA frame MCCBs with the same 3-pole form factor and similar dimensions, so the physical footprint and mounting pattern are compatible. However, the release type and ratings differ — the 3VA1150-3EF32-0AE0 uses a TM240 thermal-magnetic release and is rated for 50 A, while the 3VA1010-2ED42-0AE0 may have a different trip characteristic. Verify the release and current rating match the panel design before swapping.
